Petroleum products by supply and disposition, monthly — AI AnalysisStatistics Canada's Table 25100081 tracks monthly volumes of 31 petroleum products across 10 supply and disposition categories from January 2019 to December 2025, capturing 12,372 valid records with values ranging from -977,576 to 10,512,520 cubic metres. Total petroleum activity grew approximately Key Findings

Total Canadian petroleum supply and disposition grew by approximately 8.8% over the study period, rising from roughly 75.2 million cubic metres in January 2019 to a peak of 86.2 million cubic metres in July 2025.

The dataset contains 12,372 valid records spanning 84 monthly periods, but only 149 unique time series are populated out of 26,040 possible product-category combinations, indicating sparse coverage across the full matrix.

The distribution is heavily right-skewed, with a mean of 509,195 cubic metres approximately 8 times higher than the median of 62,716 cubic metres, and a standard deviation of 1,303,002 reflecting extreme variability driven by a few high-volume categories.

Approximately 11.5% of records (1,420 out of 12,372) contain negative values, representing adjustments, net withdrawals, or corrections in supply and disposition accounting rather than true measurement errors.

105 statistical outliers were identified using Z-score analysis (|Z| > 3), concentrated in specific product and supply/disposition combinations, pointing to episodic supply shocks or reporting anomalies in particular segments.
